In the lesson, you learned how a nerve impulse transmits through a neuron and into muscle tissue. using this knowledge, can you explain why dehydration caused joseph's muscle cramping? be detailed with your response. (hint: during dehydration, people lose a large amount of sodium.)

A muscle cramp is a painful, brief, involuntary and abrupt contraction of a muscle or muscle group.

There are several types of cramps:*Cramps from a metabolic origin are most often reported during dehydration, dyskalemia (potassium deficiency) or vitamin B1, B5 or B6 deficiency.

*Cramps due to the sport are generally linked to intense effort and occur especially if physical preparation and muscle warming have been neglected. During physical exertion, the purpose of excreted sweat is to maintain body temperature at 37 ° C, however, the loss of water is accompanied by a loss of sodium Na +. The cramp of effort (cramps during the sport) is the consequence of an overload in calcium in the muscle, generated by a lack of sodium circulating in the body (this is what happened in Joseph's body).

*Finally, cramps can be linked to other conditions that may cause them, such as circulatory disorders in the lower limbs (intermittent claudication), diabetes, multiple sclerosis, or Parkinson's disease.
